Add new object to existing array object is failing in 3.1.1

[dben1713]

Using the latest version of yq appears to break being able to add new objects to an existing array object, this was working fine as of version 2.4.1.

With this file:

applications:
  - name: app
    env:

I cannot use write to add an additional field to the 'env' object. I would expect this
yq w hello.yml "applications[0].env.hello" "world"
to output the following:

applications:
  - name: app
    env:
      hello: world

However, I am just getting the follow output:

applications:
  - name: app
    env:

I'm not sure if this is a result of the breaking change regarding "reading paths that don't exist" with the new version or not.

Adding new nodes to the array seems to work fine:
yq w -v hello.yml "applications[0].hello" "WORLD"

applications:
  - name: app
    env:
    hello: WORLD

yq w -v hello.yml "applications[0].hello.foo" "WORLD"

applications:
  - name: app
    env:
    hello:
      foo: WORLD

But I need to be able to update an existing node in the array. This is probably related to #356.
